The improved structure comprises a negative pressure tube and a suction tube, wherein the negative pressure tube is divided into a short distance section, which is close to the suction tube and is connected with the suction tube, and a long distance section, which is communicated with the short distance section; the short distance section is provided with a telescopic part. The improved structure provided by the utility model is simple and convenient, is wide in applicability, and can be adjusted in the length and bending angle of the suction tube as needed, the operation is facilitated, the operation efficiency is increased, the pain of a patient is reduced, and the risk of an operation is reduced.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of improvement structure of suction catheter.
Background technology
Medical suction tube plays suction drainage in clinical operation, supporting with suction device, for the attraction of the residual liquid of performing the operation.Suction catheter generally consists of the suction pipe of the negative tube being connected with suction device and negative tube front end, for the convenient interior residual liquid of the tissue place that inserts smoothly, suction pipe is generally hard tube, but some residual liquid remains in turning or comparison shelter, or sheltered from by perienchyma, suction pipe is difficult for touching, and the hands of holding suction pipe is easily encountered the tissue on side.The patent No. is that the Chinese patent of CN203234807 discloses uterine cavity tissue sucker on October 16th, 2013, comprise that suction catheter, lever and pipe connect, described suction catheter is divided into straightway and bending segment, described bending segment is positioned at the front portion of described suction catheter, and described bending segment becomes the angle of 10-14 ° with described straightway.Suction catheter is smooth and easy smooth, natural torsion, and in use procedure, patient, without pain, stops to cure source cross infection, protection vagina and cavity of uterus mucosa.But the flexibility of suction catheter is fixed, unadjustable, only for the bending of uterus shape, for running into the residual liquid dead angle that flexibility differs in other operations, cannot produce a desired effect; This suction catheter in use will be connected with suction device, if the negative tube being connected with suction device is too short, affects operation technique; Long words are easily impeded, and waste again material, have much room for improvement.
Utility model content
In order to solve above-mentioned deficiency, this utility model provides a kind of improvement structure of suction catheter, and simple and convenient, the suitability is wide, can in operation, regulate as required length and the angle of bend of suction catheter, and handled easily improves the efficiency of operation, reduces patient painful.
In order to achieve the above object, this utility model adopts following technical scheme: a kind of improvement structure of suction catheter, comprise negative tube and suction pipe, described negative tube is divided near described suction pipe the low coverage section being connected with described suction pipe and the long distance section that communicates with described low coverage section, and described low coverage section is provided with telescopic pars contractilis.
This utility model adopts telescopic negative tube, can regulate easily at any time the length of negative tube, handled easily person to attract operation, improves operation efficiency.
As preferably, described pars contractilis is soft plastic ripple shape pipe.
Corrugated tubes one can provide certain retractility, and two can arbitrarily rotate very freely, do not hinder and attract operation.
As preferably, between described suction pipe and described low coverage section, by connection tube, be connected, described connection tube comprises linkage section and the middle flexible changeover portion at two ends.
Connection tube plays the effect of connected sucking pipe and negative tube, hand-held suction catheter hand-held point while also operating for operator, handled easily; The setting of linkage section is in order to make connection tube be connected tightr with negative tube with suction pipe, better tightness, changeover portion is first for operator provides a good gripping point, facilitate its operation, can also be according to flexible changeover portion, drive at any angle suction pipe crooked, adapt to the attraction that different angles require.
As preferably, described changeover portion is soft pipe.
As preferably, the tube wall of described changeover portion is provided with bending ripple.
As preferably, the internal diameter of described linkage section is increased to the one end near described changeover portion gradually by the one end away from described changeover portion.
The setting of linkage section internal diameter is in order to adapt to and being connected of suction pipe and linkage section, and slightly large setting of changeover portion internal diameter can be conveniently affectedly bashful suction catheter, also convenient bending operation at any angle.
As preferably, described low coverage section and described long distance section junction are provided with identification part.
Long distance section, owing to being connected with suction device, tends to be polluted, and belongs to contaminated plug, and low coverage section is near operating-table, keep it aseptic, clean, an identification part is set in junction, can play reminding effect, also can play the effect of certain isolated polluter, reduce infection risk.
By implementing technique scheme, the utlity model has following beneficial effect: this utility model is simple and convenient, the suitability is wide, can in operation, regulate as required length and the angle of bend of suction catheter, handled easily, improves the efficiency of operation, reduce patient painful, reduce operation risk.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this utility model one embodiment;
1. negative tube; 11. low coverage sections; 111. pars contractilis; 12. long distance sections; 2. suction pipe; 3. connection tube; 31. linkage sections; 32. changeover portions; 5. identify part.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of improvement structure of suction catheter as shown in Figure 1, comprise that the negative tube 1 that is connected with suction device and front end are for the suction pipe 2 of the hard of the direct attraction use of doctor's operation, described negative tube 1 is divided into the close suction pipe 2 of front end the low coverage section 11 connected with suction pipe 2 and the long distance section 12 being connected with suction device with rear end, between low coverage section 11 and long distance section 12, by identification part 5, separates.In low coverage section 11, be provided with one section of telescopic pars contractilis 111, the tube wall of pars contractilis 111 is corrugated, by certain dynamics, can stretch or its length of compression adjustment.Between straw part 2 and low coverage section portion 11, by connection tube portion 3, be connected, described connection tube 3 comprises linkage section 31 and the middle flexible changeover portion 32 at two ends, linkage section 31 is hard material formation, and changeover portion 32 is soft pipe, can be crooked arbitrarily, to regulate the angle of suction pipe 2, or on the tube wall of the changeover portion 32 of hard, bending ripple is set, also can be used for adjusting angle.The internal diameter of linkage section 31 is increased to the one end near described changeover portion 32 gradually by the one end away from described changeover portion 32, and the internal diameter of changeover portion 32 is identical with the maximum inner diameter of connection tube 31.
